A novel diazoacetate monomer (1) carrying tert-butyloxycarboryl (Boc) protected D-prolinol ester was designed and synthesized successfully. Mol. weight-controlled polymerization of 1 using the complex of π-allylPdCl coordinated Wei-phos (LR) ligand gives a series of helical polycarbenes (poly-1ms) with well-defined mol. weights (Mns) and low polydispersity (Mw/Mns). Removing the protecting Boc groups on the D-prolinol ester pendants leads to the formation of helical poly-1m-As, which showed high optical activity. Furthermore, the poly-1m-As showed high catalytic ability on asym. Michael addition reaction (up to 76% ee and 94/6 dr). Both the enantioselectivity and diastereoselectivity of the Michael addition reaction were increased comparing to D-prolinol as catalyst. Moreover, the helical polycarbene catalyst can be easily recovered and reused at least four times without significant loss of its enantioselectivity and diastereoselectivity.

The authors recently reported the synthesis and biol. activity of the sulfonamide I, the first potent 5-HT7 receptor antagonist with 100-fold selectivity over a wide range of receptors. More recently a series of tetrahydrobenzindoles have been reported as potent 5-HT7 receptor antagonists, although selectivity over 5-HT2 receptors was only 50-fold. In this communication, the authors report the further optimization of I by conformational restraint of the side chain which has led to more potent and selective compounds, exemplified by II. II was evaluated in a functional model of 5-HT7 receptor activation by examination of adenylyl cyclase activity in HEK 293 cells stably expressing the human 5-HT7(a) receptor.

Compound: 2,5-Diphenyloxazole, is researched, Molecular C15H11NO, CAS is 92-71-7, about Attempting to prepare a plastic scintillator from a biobased polymer. Author is Hamel, Matthieu; Lebouteiller, Guillaume.

A new plastic scintillator was prepared from a renewable polymer source. It is composed of the mighty 2,5-diphenyloxazole and 1,4-bis(2-methylstyryl)benzene mols. (PPO and bis-MSB), acting as primary and secondary fluorophores, resp., together dissolved in a polylactic acid matrix-PLA. This polymer is indeed considered as the biomass-based equivalent of petroleum-derived plastics in terms of mech. and optical properties. Subsequent to the bis-MSB emission, the emission wavelength is centered around 424 nm and the fluorescence decay time is in the nanosecond range. The material was fully characterized, and its scintillation performances were compared to a com. PVT-based plastic scintillator: EJ-200. Like polystyrene- or polyvinyltoluene-based scintillators, the material displayed a good response linearity with the energy of the incident gamma-ray. However, the observed scintillation yield was rather modest, with a reported 500 ph/MeV value when excited with a gamma-ray-emitting 60Co source. This preliminary test could pave the way to new and renewable polymers for unexpected applications such as nuclear physics.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2,5-Diphenyloxazole( cas:92-71-7 ) is researched.Recommanded Product: 92-71-7.Liu, Chengwei; Ji, Chong-Lei; Zhou, Tongliang; Hong, Xin; Szostak, Michal published the article 《Bimetallic Cooperative Catalysis for Decarbonylative Heteroarylation of Carboxylic Acids via C-O/C-H Coupling》 about this compound( cas:92-71-7 ) in Angewandte Chemie, International Edition. Keywords: chemoselective synthesis heterobiaryl decarbonylative heteroarylation carboxylic acid heteroarene; bimetallic cooperative catalysis chemoselective synthesis heterobiaryl; C−O/C−H bond activation; bimetallic catalysts; carboxylic acids; decarbonylation; heteroarylation. Let’s learn more about this compound (cas:92-71-7).

Cooperative bimetallic catalysis is a fundamental approach in modern synthetic chem. We report bimetallic cooperative catalysis for the direct decarbonylative heteroarylation of ubiquitous carboxylic acids via acyl C-O/C-H coupling [e.g., benzoxazole + benzoic acid → 2-phenylbenzoxazole (92%)]. This novel catalytic system exploits the cooperative action of a copper catalyst and a palladium catalyst in decarbonylation, which enables highly chemoselective synthesis of important heterobiaryl motifs through the coupling of carboxylic acids with heteroarenes in the absence of prefunctionalization or directing groups. This cooperative decarbonylative method uses common carboxylic acids and shows a remarkably broad substrate scope (>70 examples), including late-stage modification of pharmaceuticals and streamlined synthesis of bioactive agents. Extensive mechanistic and computational studies were conducted to gain insight into the mechanism of the reaction. The key step involves intersection of the two catalytic cycles via transmetalation of the copper-aryl species with the palladium(II) intermediate generated by oxidative addition/decarbonylation.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures.

New members of a previously reported series of 3-pyridyl ether compounds are disclosed as novel, potent analgesic agents acting through neuronal nicotinic acetylcholine receptors. Both (R)-2-chloro-5-(2-azetidinylmethoxy)pyridine (ABT-594, I) and its S-enantiomer (II) show potent analgesic activity in the mouse hot-plate assay following either i.p. (i.p.) or oral (po) administration, as well as activity in the mouse abdominal constriction (writhing) assay, a model of persistent pain. Compared to the S-enantiomer and to the prototypical potent nicotinic analgesic agent (±)-epibatidine (III), I shows diminished activity in models of peripheral side effects. Structure-activity studies of analogs related to I and II suggest that the N-unsubstituted azetidine moiety and the 2-chloro substituent on the pyridine ring are important contributors to potent analgesic activity.
